1. Efficient power conversion: The cornerstone driving household electricity

The most fundamental and crucial function of an inverter is to efficiently and stably convert the direct current generated by solar panels under sunlight or stored in energy storage batteries into high-quality pure sinusoidal 220V (or regional standards) alternating current that meets the national power grid standards and is suitable for household appliances.

2. Intelligent energy storage management: The core of optimizing energy utilization

Modern household wall inverters are usually closely integrated with energy storage battery systems and play the role of the "energy brain" of the home. It can intelligently manage and schedule the charging and discharging process of energy storage batteries. Specifically:

Intelligent charging and discharging strategy: The inverter will automatically optimize the charging and discharging logic based on the real-time monitored photovoltaic power generation capacity, the size of the household electricity load, and the preferences set by the user.

Battery health management and protection: The inverter is built in or works in coordination with an external battery management system (BMS) to provide comprehensive protection for energy storage batteries. This includes preventing abnormal conditions such as overcharging, over-discharging, over-temperature, overcurrent and short circuit of the battery, ensuring that the battery operates within a safe working range, thereby maximizing the battery's service life and guaranteeing system safety.

3. Flexible operation mode: Ensure friendly interaction between power supply and the power grid

To adapt to different electricity demands and external power grid conditions, household wall-mounted inverters usually support multiple operation modes and can achieve intelligent switching:

Grid-connected operation mode: In this mode, the electricity generated by the household photovoltaic system is prioritized for self-use, Excess electricity fed into the power grid is beneficial.

Off-grid/standby power (UPS) mode: When the public power grid experiences a failure, power outage or unstable voltage, the inverter can quickly (usually within milliseconds) switch to off-grid mode, using the stored electricity in the energy storage battery to provide uninterrupted power supply for the critical loads in the household, greatly enhancing the reliability of household electricity usage and emergency response capabilities.

Multiple strategy modes such as photovoltaic priority, energy storage priority, and municipal power priority: Users can set different energy utilization priorities according to their own needs to maximize energy efficiency.

4. Smart monitoring and convenient control: The energy manager at your fingertips

To enable users to clearly understand and conveniently manage their home energy systems, wall-mounted inverters are usually equipped with advanced human-machine interaction functions:

Real-time data monitoring: Through the built-in LCD screen of the inverter software or the mobile phone APP, key information such as photovoltaic power generation capacity, daily/monthly/annual power generation, household electricity load, energy balance (SOC) of energy storage batteries, health status (SOH), and current operating mode can be viewed in real time

Remote control and parameter setting: Through network connection, users can remotely adjust the parameters of the inverter, switch operation modes, upgrade firmware, start and stop control, etc., which greatly enhances the convenience of use and the flexibility of the system.

Fault Diagnosis and Alarm: The inverter is equipped with a self-diagnosis function. Once it detects abnormal system operation or potential faults, it will cut off the power for protection and promptly send an alarm to the user through APP push or indicator lights, etc., to notify the user to troubleshoot and repair in time.

5. System Security and Renewable Energy Optimization

In addition to the above-mentioned core functions, the inverter is also committed to enhancing the safety and energy utilization efficiency of the overall system:

Maximum Power Point Tracking (MPPT) : For photovoltaic systems, the efficient MPPT algorithm built into the inverter can track the optimal operating voltage and current of the solar panels in real time, ensuring the best working condition of the solar panels and maximizing the power generation efficiency.

Comprehensive electrical protection: Equipped with multiple electrical protection functions, such as input overvoltage/undervoltage protection, output overload/short circuit protection, lightning protection, islanding effect protection, etc., to ensure the safe and stable operation of the inverter and the entire household power system.
